[OE-core] UBI filesystem creation fails silently with 4k erase size

[Mike Looijmans]

I have a NOR chip that reports a 4k erase size, so in my machine.conf I entered:

MKUBIFS_ARGS = "-m 1 -e 3968 -c 7040"
UBINIZE_ARGS = "-m 1 -p 4096"
UBI_VOLNAME = "qspi-rootfs"


When I create an image with "ubi" in the IMAGE_FSTYPES, the build runs and 
does not report any error, however it did NOT create the ubi filesystem image.

If I change the parameters for a 64k flash using:

MKUBIFS_ARGS = "-m 1 -e 65408 -c 440"

the ubi filesystem is created (both ubifs and ubi files).


Where can I find what went wrong? I'd expect big read error messages telling 
me that it failed to create an image for my device, but I cannot find such 
message anywhere.

So my questions are:

1) Why is there no error message when image creation fails?
2) Where is the log/output from the mkfs.ubi commands?
2) What could be wrong with my mkubifs parameters?

Mike.
